IPC: B21B19/04
Filed: 1991-02-27
Abstract: PURPOSE:To prevent the tube end crack and the rolling trouble, and to improve the rolling work efficiency and the yield of a product, at the time of manufactur ing a seamless alloy steel tube. CONSTITUTION:Common steel square pieces 3,4 having substantially the same cross section as an alloy steel square billet 1 are joined to the tip and the rear end of the alloy steel square billet, respectively and subjected to push piercing rolling. Subsequently, after at least stretch rolling is executed, the common steel, part is eliminated. As for the plain steel, a fall of deformability caused by a temperature fall is small, therefore, it does not occur that a tube end crack, a bite failure, a run out failure, etc., are generated. Also, as for the front end part and the rear end part of the alloy steel square billet, heat radiation is prevented by the plain steel square piece, therefore, a temperature fall in the course of rolling is small. Accordingly, a fall of deformability is also small, and a crack, etc., are not generated in the tip and the rear end part of the tube.

Title: Electron beam scanning method
Inventor: MURAKOSHI HISAYA
IPC: H01J37/153
Filed: 1987-02-18
Abstract: PURPOSE:To reduce the electrification of a sample and avoid the malfunction of the automatic focusing or automatic astigmatism correction by changing the radius of a circular scan in stages when circularly scanning an electron beam on the sample. CONSTITUTION:A circular scan generating unit 11 is constituted of a cosine wave current generating unit and a sine wave current generating unit. The amplitude of a deflecting amplifier 12 is variably set at every cycle or more of the sine wave and cosine wave current by a multiplying factor switching circuit 13. The current is fed to an X deflector 3X and a Y deflector 3Y respec tively from the amplifier 12 thus set. As a result, an electron beam 2 performs a circular scan concentrically on a sample 5 while the radius is changed in stages for every cycle. Next, for the automatic astigmatism correction, current values ISX, ISY of astigmatism correction oils 15X, 15Y are variably set respec tively via astigmatism correction coil drive circuits 14X, 14Y, and optimum current values ISXept, ISYept are determined in the same procedure as that for the automatic focusing. Accordingly, the electrification of the sample is reduced, and the malfunction of the automatic focusing or automatic astigmatism correc tion can be avoided.

Title: Method for recovering rhodium from copper sulfate solution
Inventor: SUGIMOTO MASATO
IPC: C25C1/20
Filed: 1994-03-03
Abstract: PURPOSE:To selectively and efficiently recover rhodium by subjecting a rhodium- contg. copper sulfate soln. to electrolytic deposition treatment under certain conditions. CONSTITUTION:A copper sulfate soln. having <=40g/l concn. of copper which is <=250 times that of rhodium is electrolyzed in an electrolytic cell under the conditions of 100-300g/l concn. of sulfuric acid and 200-400A/m<2> current density. A deposit. settled on the bottom of the cell by this electrolysis is drawn out, copper in the deposit is dissolved in a sulfuric acid soln. having 100-200g/l concn. of sulfuric acid and rhodium is separated. In order to increase the rate of recovery of rhodium, it is necessary to discharge settling copper powder from the cell in an earlier stage. It is preferable that the cathode of the cell is exchanged according to the concn. of copper and that of rhodium in the electrolytic soln. or two or more cells are arranged in series. The reason for the exchange or arrangement is that rhodium electrodeposited on the cathode is repeatedly treated as a metal for dissolution of the scrap and the rate of recovery of rhodium is reduced.
